MACHINE FOR MANUFACTURING FILTER MOUTHPIEICE CIGARETTES Original Filed June 22, 1954 United States Patent MACHINE FoR MANUFACTURING FILTER MOUTHPIECE CIGARETTES Kurt Kiirber, Hamburg-Bergedorf, Germany, assignor to Kui-t Kiirber & Co. K.G., Hamburg-BergedorflGermany @laims priority, application Germany September 22, 1953 3 Claims. Cl. 131-94 The invention relates to improvements in the manufacture of filter mouthpiece cigarettes or the like, and has particular reference to a machine by which an assemblage consisting of two cigarettes arranged in spaced axial alinement with a mouthpiece .of double length therebetween is formed on rotary members and the mentioned cigarette parts are joined together by a glued connecting band and thereafter the assembly is divided in the center of the mouthpiece so that two cigarettes each having a mouthpiece are produced. This invention is a division of applicants copending patent application Serial No. 438,532 filed on the 22nd day of June 1954 and now'Patent No. 2,830,595 granted April 15, 1958.

The present invention differs basically from known machines of this kind in that first the mouthpieces of doulale length are deposited on a rotary member and are brought into contact with the glued connecting bands, whereupon the latter are deposited upon a second rotary member on which the cigarettes supplied from two sides are laid down on the end portions of the connecting bands projecting beyond the mouthpieces. The end portions of the connecting bands extending laterally beyond the ends of the cigarettesmouthpiece-groups are then wrapped around the abutting joints between the mouthpieces and the two adjacent cigarettes on the same rotating member, thereafter the assemblages thusformed are servered in the center of the mouthpiece and the mouthpiece cigarettes formed in this manner are conveyed to a place of deposit.

This and other objects of the invention are described in the following specification and illustratedin the accompanying. drawings showing a preferred embodiment of a machine of the invention:

In the drawings:

Fig. 1 illustrates diagrammatically a side view of a machine, partly shown in sectional view; and,

meeting passage 2c which communicates with a source of suction through a duct 2d. The mouthpieces are thus retained in the grooves 2a by means of the applied suction force, after they have passed the guide strips 3c, 3d.

At the point M2 glued connecting bands 4a are afiixed to the mouthpieces, which bands, are cut-off at 5 from a paper tape 4 unwinding between rollers 5a from a supply spool 4b in the direction of the arrow 4b. The individual bands 4a are deposited on a rotary suction drum 6.

The suction drum 6 also is provided with suction ducts 6a which communicate through a connecting duct 6b with a suction pipe 6c and thus retain the severed connecting bands 4a on the drum 6. These connecting bands are at 4a coated by a drum 7 with an adhesive which by Fig. 2 represents a top view, with the magazines for mouthpieces and cigarettes cut away for sake of clarity. Referring first to Fig. 1, the magazine 1 contains the mouthpieces Mof double-length whichpieces are deposited at M1 into trough-like grooves 2a on the circumference of a rotary drum2 rotating in the direction of the arrow 2' (counterclockwise).

In order to obtain an accurate placement of the mouthpieces into the grooves 2a,, there are provided lateral guide plates 3a and3b (Figs. 1, 2) between which said mouthpieces M are passed through when the drum 2 revolves, permitting the mouthpieces to accurately adjust themselves in the grooves 2a of the drum 2. There are also provided two arcuate strips 30 and 3d which prevent the mouthpieces from dropping out of the grooves when the drum is rotated.

Suction ducts 2b communicate with the bottoms of the grooves 2a in a manner known per se, which ducts before the grooves 2a have been rotated beyond the guide Strips 3c, 3d are brought into communication with a conthe intermediary of a drum 8 is supplied by a drum 9 with adhesive contained in the receptacle 10.

After the mouthpieces M together with the connecting bands 4a adhering thereto have been moved by the rotary drum 2 from the place M2 to the place M3, the connecting bands together with the mouthpieces adhering thereto are deposited on a rotary drum 1 1 which rotates clockwise in the direction of the arrow ll'.

The rotary drum 11 is so wide that it is possible to place groups of two axially spaced and axially alined cigarettes Z thereon, with the mouthpiece M therebetween. For this purpose there are provided at each of the two ends ofthe mouthpieces M around the periphery of the drum 11 two rings 11a, 11b and 110, .11a',respectively, which are provided with axially extending grooves. At the point Z the cigarettes Z are deposited in pairs into the grooves in these rings 11a, 11b and 11c, 11d, respectively, from two magazines12a and 1% (see also Fig. 2) so that'they come to rest with one of their: ends, which face the mouthpieces M upon the projecting end portions of the connecting bands 4a to the center portions of which the mouthpieces are adhering.

Furthermore the provision is made that the discharge supports 12a and 1212 of the magazines 12a and 12b are inclined as shown at 12a and 1212 (see Fig. 2), towards the mouthpiece M, in order to assure that the cigarettes Z are moved into abutting engagement with the endsof the mouthpiece. The cigarettes leaving the retained thereon by means of air suction, which in a well known. manner is provided through suctionducts 11e which are in communication with suction pipe 14 by a connecting channel 13.

After the cigarettes Z abutting in lengthwise direction against the end faces of the mouthpieces M have been deposited at Z1 on theconnecting band, the lattenis wrapped around the mouthpiece and around the end pottions of the cigarettes contacting said pieces by means of folding elements. This is accomplished by the folding.

elements 14a and 14b (shownin Fig-1 indotted lines each of which elements is controlled bya'. stationary cam" After the connecting band has been completely wrapped around the cigarettes and the mouthpiece, the latter is cut through at its center by means of a rotary cutting knife 3 16; Thereafter the suction ducts move out of communication with the connecting duct 13, so that the now completed mouthpiece cigarettes can be deposited onto a chute 17 which directs thecigarettes onto a conveyor belt 18 which carries the cigarettes to ,a collecting magazine not shown.

The described machine is driven by a motor 19 which drives the suction drum 6 through an endless belt or chain drive 20, and the conveyor belt 18 through another endless belt 21, while the drum 11 is driven by an endless belt 22 or the like. Mounted on the shaft of the rotary drum 11 is mounted a gear 23 (also see Fig. 2) which is in engagement with a gear 24 on the shaft of the rotary drum 2. The rotary cutter 16 is driven by means of the chain or belt drive 25 or by means of a separate motor.

In the described example of the embodiment of the invention the depositing of the mouthpiece M onto the drum 2and the depositing of the cigarettes Z onto the drum 11 is brought about by'a direct feed from the magazines.

Furthermore, in the shown and-described example of embodiment of the invention the connecting band 4a together with the double length filter mouthpiece adhering thereto is delivered at the point M3 to the drum 11 in such a manner that it comes to lie against the drum circumference in plane and flat condition.

The invention is not restricted to the details of the foregoing example. It will be apparent to those skilled inthe art that variations and modifications may be made to the specific construction described in that example, without departing from the invention or the scope of the appended claims.
